A Tractor Beam to Levitate the Largest Object Yet

A Tractor Beam to Levitate the Largest Object Yet

The world’s most powerful tractor beam just lifted a 2 centimeter ball, but could it make levitating humans a reality?

The world’s most powerful acoustic tractor beam could pave the way for levitating humans.

“Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids. For the first time University of Bristol engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam.”
